The required probability that she rolls a 1 both times is 1/36.
Fatima rolls a number cube 2 times. To find the probability that she rolls a 1 both times.
Probability can be defined as the ratio of favorable outcomes to the total number of events for a system of certain events.
Probability = frequency of favorable outcome / Sample space.
Fatima rolls a number cube 2 times.
For a roll sample space = { 1 2 3 4 5 6}
n(sample space) = 6
Favorable outcome (rolls a 1) = 1
Required probability for 1 = 1/6
Probability for rolls a 1 both times.= 1/6 *1/6
= 1/36
Thus, the required probability that she rolls a 1 both times is 1/36.
