    Answer:
    This can be solved according to the Bernoulli binomial distribution:
    C(5,3) x (1/2)^3 x [1-(1/2)]^(5-3)
    = 10 x (1/2)^5
    = 10/32
    = 5/16
    = 0.3125what is the Bernoulli binomial distribution?Answer: You can refer to a book about probability and statistics. Alternatively, you can simply Google "binomial distribution" for a quick answer.
