Assume we have a binomial random variable There are six tria

Assume we have a binomial random variable. There are six trials completed. The probability of a success is 0.4. What is the probability of finding Y=2 successes?

Solution

P( two successes in 6 trials)

= ⁶C₂ (0.4)² (0.6)⁴

= 0.3110

Hope this helps.
