Answer:
0.578
Step-by-step explanation:
If you pick three burritos at random, find the probability of the given event. (Round your answer to three decimal places.)
Given that there are 14 orders at the ratio by of:
6 with hot peppers
8 without hot peppers
At most two have hot peppers.
Binomial Problem with n = 3 ; p(hot) = 6/8
P(0<= x <=2) = 1 - P(x = 3)
= 1 - (6/8)^3
= 1 - ( 3/4 )^3
= 1 - ( 27/64 )^3
= 1- (37/64)
= 1 - 0.421875
= 0.578125
= 0.578
1/3 chose hamburger and 3/8 chose pizza
add them together
1/3 + 3/8
get a common denominator of 24
1/3 *8/8 + 3/8 *3/3
8/24 + 9/24
17/24
Choice D
In the attachment this is how i did it! ~Best of Luck~
