We have to calculate the probability of picking a 4 and then a 5 without replacement.
We can express this as the product of the probabilities of two events:
• The probability of picking a 4
,
• The probability of picking a 5, given that a 4 has been retired from the deck.
We have one card in the deck out of fouor cards that is a "4".
Then, the probability of picking a "4" will be:
The probability of picking a "5" will be now equal to one card (the number of 5's in the deck) divided by the number of remaining cards (3 cards):
We then calculate the probabilities of this two events happening in sequence as:
Answer: 1/12
Answer:
2,4 and 7 do not form a triangle
Step-by-step explanation:
To form a triangle, knowing the 3 sides, then
The sum of any 2 sides must be greater than the third side
Consider 2, 4, 7
2 + 4 = 6 < 7
2 + 7 = 9 > 4
4 + 7 = 11 > 2
Since 2 + 4 < 7
Then these 3 sides would not form a triangle
Answer:
Look below
Step-by-step explanation:
First, use order of operation or the three o's. That tells you to do what's in the parentheses first. Find out what the x next to the 2 is. Then subtract. If you look at the key, it shows you most of the answer. One black and one white both equal 1. Solve the question then sneak a calculator and simplify. Use the blocks to drag down as much as your final answer is.
