Using the Binomial Probability table, find P (X) when n = 7, X < 3, and p = 0.5 A. 0.273 B. 0.500 C. 0.227 D. 0.773

0.227

Step-by-step explanation:

Given that X is binomial with n=7 and p = 0.5

To find the probability for P (X<3)

i. e. we have to find prob as = P (x=0,1,2)

=P (X=0) + P (X=1) + P (x=2)

P (X=r) = 7Cr (0.5) ^7

Using binomial table we find prob

P (X<3) = 0.2265

Round off this to 3 decimals as

0.227

Hence answer is 0.227
