To find the probability of rolling a 2 on the number cube and the coin landing heads up, we need to multiply the probabilities of each event happening.
The probability of rolling a 2 on the number cube is 32 (times rolled) out of 100 (total rolls), which is 32/100 or 0.32.
The probability of the coin landing heads up is 55 (times heads) out of 100 (total coin flips), which is 55/100 or 0.55.
Therefore, the probability of rolling a 2 on the number cube and the coin landing heads up is 0.32 * 0.55 = 0.176 or 17.6%.
Converting 17.6% to a fraction, we get 17.6/100 = 1760/10000.
So, the probability of rolling a 2 on the number cube and the coin landing heads up is 1760 over 10000.
