possibilities are
A) 3/70
B) 3/75
C) 1/35
D) 2/70
A) 3/70
B) 3/75
C) 1/35
D) 2/70
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
3/15 * (3-1)/(15-1) = ?
3/15 * (3-1)/(15-1) = ?
1/35
There are 3C2 ways in getting both toy cars, and our sample space is 15C2.
Thus, the probability becomes: 3C2/15C2 = 1/35
