Assuming that the two events are independent (i.e. the fact of scoring the first time does not influence the probability of scoreing the second time), the probability of scoring the first time is equal to the probability of scoring the second time.and the joint probabililty is the product of thw two probabilities.
Probability of scoring the first time = 0.30
Probability of scoring the second time = 0.30
Joint probability = 0.30 * 0.30 = 0.09
Then, the answer is 0.09.
