Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26
N /(n*10^n)
So 3 would be
3/(3×1000)=1/1000=.001
Because they have lettters the (p's) go together which is -6p and then you have the +15 left so you add that on the end , your answer is -6p + 15
