Question

A school offers four extra curricular activities: band, yearbook, basketball, and art. If two students choose randomly, what is the probability that they both end up on the yearbook staff?

Express the probability as a decimal rounded to two decimal places.

Answer 1

Each has a probability of 1/4 of joining the yearbook staff. The probability that both indpendently choose that activity is the product of their individual probabilities:
.. (1/4)*(1/4) = 1/16 ≈ 0.06
