Answer: 560
Step-by-step explanation:
There are [20, 22, 24, 26, 28]: 5 even integers for each ten numbers.
The 20's set can be written as 5*20 + (2+4 + 6 + 8) = 5*20 + (20) = 120
The 30's can be written: 5*30 + 20 = 170
40's: 5*40+20 = 220
50's: 5*50+20 = 270
60's: 5*60+20 = 320
Each set is incremented by 50
We want the sets for 20, 30, and 40, plus the number 50.
(120+170+220+50) = 560
You can also do this in Excel (attached). Set the first cell to 20, the next cell below equal to the cell above plus 2. Then draw the second cell down until you've reached 50. Then sum the cells to arrive at 560.
Answer:
<em>statements 3 and 4 are correct.</em>
Step-by-step explanation:
(1)
The probability of choosing cured pasta and bear= probability that the card is king.
Hence, The probability of choosing cured pasta and bear=
Probability of choosing baked cucumber and lime mutton=probability that the card is 3.
as there are 4 cards that are '3'.
Hence Probability of choosing baked cucumber and lime mutton=
as both the probabilities are equal.
Hence statement 1 is incorrect.
(2)
The probability of choosing gooseberry & passion fruit cheesecake= Probability taht the card is ace.
as there are 4 cards which are ace out of 52 cards.
Hence, The probability of choosing gooseberry & passion fruit cheesecake=
probability of choosing poached fennel & lemon alligator=Probability that the card is a face card.
As there are 12 face cards out of 52 cards.
Hence, probability of choosing poached fennel & lemon alligator=
Hence, the probability of choosing gooseberry and passion fruit cheesecake is smaller than the probability of choosing poached fennel & lemon alligator.
Hence statement 2 is false.
(3)
The probability of choosing a praline wafer=probability that the card is a diamond.
as there are 13 diamond cards out of 52 cards.
The probability of choosing a praline wafer=
the probability of choosing poached fennel & lemon alligator=Probability that the card is a face card.
As there are 12 face cards out of 52 cards.
Hence, probability of choosing poached fennel & lemon alligator=
Hence, The probability of choosing a praline wafer is greater than the probability of choosing poached fennel & lemon alligator.
Hence statement 3 is correct.
(4)
The probability of choosing pressure-cooked mushroom & garlic chicken =probability that the card is red.
As there are 26 red cards out of 52 cards.
Hence,
The probability of choosing pressure-cooked mushroom & garlic chicken =
probability of choosing an oven-baked apple & lavender calzone =probability that the card is black.
As there are 26 red cards out of 52 cards.
Hence, probability of choosing an oven-baked apple & lavender calzone=
Hence, The probability of choosing pressure-cooked mushroom & garlic chicken and the probability of choosing an oven-baked apple & lavender calzone are the same.
Hence statement 4 is true.
(5)
The probability of choosing pressure-cooked mushroom & garlic chicken =probability that the card is red.
As there are 26 red cards out of 52 cards.
Hence,
The probability of choosing pressure-cooked mushroom & garlic chicken =
the probability of choosing a praline wafer=probability that the card is a diamond.
as there are 13 diamond cards out of 52 cards.
The probability of choosing a praline wafer=
Hence, the probability of choosing pressure-cooked mushroom & garlic chicken and the probability of choosing a praline wafer are not same.
Hence, statement 5 is not correct.
