Question

MUST SHOW ALL WORK TO RECEIVE CREDIT. Determine the following probabilities by use of the table of binomial probabilities:

e. P(X 2: 8 I n =50, p = 0.80)

Solution

sol )P(X 2: 8 I n =50, p = 0.80)

using Binomial table values

P(X =2, n =50, p = 0.80)=2.20676381741152E-31

P(X=3, n =50, p = 0.80)=1.41232884314337E-29

P(X=4, n =50, p = 0.80)=6.63794556277385E-28

P(X=5, n =50, p = 0.80)=2.44276396710078E-26

P(X=6, n =50, p = 0.80)=7.32829190130234E-25

P(X=7, n =50, p = 0.80)=1.84254196375602E-23

P(X=8, n =50, p = 0.80)=3.96146522207544E-22
