(1.79 x 10^-34, or 1.79e-34)
Step-by-step explanation:
If you flip a coin and roll a 6-sided dice 100 times, the probability that you will land tails and roll a 3, 20 times, is very small. The probability of landing tails on a coin toss is 1/2, and the probability of rolling a 3 on a 6-sided dice is 1/6. Therefore, the probability of landing tails and rolling a 3 in a single flip and roll is 1/2 * 1/6 = 1/12.
Since you are doing this 100 times, the probability that you will land tails and roll a 3, 20 times, is (1/12)^20 * 100 = 1.79 x 10^-34. This means that it is highly unlikely that you will land tails and roll a 3, 20 times, out of 100 flips and rolls.
