Answer:
1/100
Explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
the probability = (number of yellow marbles / total number of marbles) x (number of yellow marbles / total number of marbles)
total number of marbles = 1 + 5 + 4 = 10
(1/10) x (1 / 10) = 1 /100
