Question

Raghu tosses a coin 6 times. The probability that the number of times he gets heads will not be greater than the number of times he gets tails is.

Answer 1

Answer:

0.34375

Step-by-step explanation:

X = number of heads obtained

X~B(6,0.5)

the number of times he gets heads will not be greater than the number of times he gets tails is implies 2 heads and 4 tails.

P(X<=2) = 6C0 * (0.5)^6 + 6C1 * (0.5)^5 * (0.5) + 6C2 * (0.5)^4 * (0.5)^2

= 0.34375
