Answer:
1.563
Step-by-step explanation:
Given :
Probability of head, p = 0.64
Number of flips it would take for tail to appear first :
Treatting the question as a geometric function :
Using the relation :
1 / p
Expected number of flips until first tail :
1 / P = 1/ 0.64 = 1.5625
E(x) = expected number of flips until first tail = 1.563
Well, you know just by looking at it because it ends in an even number. Like, the greatest common factor of 4 is 2, 1.) Because no other number can "go into it," and 2.) Because it's even.

Answer:
11/36
Step-by-step explanation:
Here are the steps:
Step 1: Find a common denominator for both of the fractions
4/9 --> 27/36 (Multiply top and bottom by 4)
3/4 --> 16/36 (Multiply top and bottom by 9)
This is the smallest common denominator
Step 2: Subtract:
27/36 - 16/36 = 11/36
Soo...
x = 11/36
