a study found 37% of a new technique resulted in pregnancy and in that technique 25% resulted in multiple births
what is the probabilty that the new technique produced a pregnacy and multiple births
what is probability that a random selected pregnancy did not produce multiple births
would it be unusual for a random selected new birthing technique to produce pregnancy and multiple births

Probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
Preg. and mult. = .37 * .25 = ?
Preg. and not mult. = .37 * (1.25) = ?
