Answer:
0.125, 0.375, 0.375, 0.125
Step-by-step explanation:
For a binomial distribution :
nCk * p^k * (1 – p)^(n – k)
P(0 successes) = 0 head, k = 0
n = 3 = number of flips
P(success) = 0.5
3C0 * 0.5^0 * 0.5^3
1 * 0.5^0 * 0.5^3 = 0.125
P( 1 success) = 1 head, k = 1
n = 3 = number of flips
P(success) = 0.5
3C1 * 0.5^1 * 0.5^2
3 * 0.5^1 * 0.5^2 = 0.375
P(2 successes) = 2 head, k = 2
n = 3 = number of flips
P(success) = 0.5
3C2 * 0.5^2 * 0.5^1
3 * 0.5^2 * 0.5^1 = 0.375
P(3 successes) = 3 head, k = 3
n = 3 = number of flips
P(success) = 0.5
3C3 * 0.5^3 * 0.5^0
1 * 0.5^3 * 0.5^0 = 0.125
Answer:
0.125, 0.375, 0.375, 0.125
second part is 0.5
