Answer:
a) 0.076
b) 0.5
c) 0.084
d) 0.25
e) 0.00024
f) 0.156
Step-by-step explanation:
a) In an ordinary deck there are 4 aces. The probability of getting an ace is given by:
n: options for an ace = 4
N: total number of cards = 52
The probability is 7.6%
b) On the first 100 positive integers, there are 50 odd integer numbers. Then you have:
The probability of getting an odd number is 50%
c) From a total of 365 day in the year, May has 31 day. Then you have:
The probability is 8.4%
d) In this case you have two events. To get an odd number with the sum of the number of two dices you need and odd number in one dice and a pair number in the other dice.
The probability is the product of the occurrence of both events. The probability for an odd number is 1/2 and for a pair number is 1/2.
The probability is 25%
e) To obtain Head 6 times in a row, the probability is:
Probability of 0.024%
f) To get Head 4 times from 5 flights, you first calculate the probability for 1 head in five flips:
There are 5 forms of getting 4 Heads for 5 flips, then you have:
Te probability is 15.6%
Answer:
ok, I looked at it lol ( it's A btw)
Step-by-step explanation:
Answer:
n to the power of 2
Step-by-step explanation:
baiscally just subtract 6-4 to get 2
If x is the third side, then x is between 5-3 = 2 and 5+3 = 8. The value of x cannot be equal to 2, or it can't be equal to 8 either.
So 2 < x < 8. The following answer choices fit this inequality:
choice B) 6 cm
choice C) 4 cm
The other answer choices are outside of the interval 2 < x < 8
So that's why the answers are choice B and choice C.
13:38. There are 13 spaces available and 38 spaces already occupied. 13:38 cannot be simplified, as 13 is a prime number. Hope this helps! ~<em>ArchimedesEleven</em>
