Answer:
if this is finish the problem then
"his friends decided to order pizza for lunch. one of his friends said they wanted to eat 5 slices. the other one said he wanted 3 and the last one said they must wanted 7 while little Blake just wanted 2. how many boxes of pizza would Blake have to order."
MY answer: zero because Blake made them pay for their own boxes. they didn't want to at first but then they saw the knife Blake was holding in his hand and decide that if they want to live they must buy their own pizza and give him some or theirs
Its easier to find the complement of that instead
so you find the probability of 1 and 0
The .2 in the answer is the probability of each question 1/5
(10 C 0) x .2^0 (1-.2)^10-0=.1074
(10 C 1) x .2^1 (1-.2)^10-1=.2684
.2684+.1074=.3758 and that's the complement
so 1 - .3758= .6242
I too have a stats exam on this tomorrow lol
Answer:
The equation is
15x = 610
Step-by-step explanation:
A dime is 10 cents while a nickel is 5 cents
$6.10 is same as 610 cents
Let the number of dimes and number of nickels be x
10x + 5x = 610
15x = 610
