Assume that X is a binomial random variable with n = 4 and p = 0.68. Calculate the following probabilities. (Do not round intermediate calculations. Round your final answers to 4 decimal places.) a. P(X = 3) b. P(X = 2) c. P(X ? 2)

Step 1
68)^3 \times (1-0.68)^{4-3}\] \[P(X = 3) = 4 \times (0.68)^3 \times (0.32)^1\] \[P(X = 3) = 4 \times 0.314432 \times 0.32\] \[P(X = 3) = 0.40247\] Show more…

Find the normal approximation for the binomial probability $\quad P(x=4,5),$ where $n=14$ and $p=0.5$ Compare this to the value of $P(x=4,5)$ obtained from Table 2.
