6 |
Step by Step Explanation:
- Let us assume that S, E, and P are the sample space, event and probability of getting a number less than 4 by throwing a dice, respectively.
S = {1, 2, 3, 4, 5, and 6}
E ={1, 2, 3} - P(E) =
n(E) n(S)
(Since, P(E) is the probability of getting an event E, n(E) is the number of elements in the event E and n(S) is the number of elements in the sample space S )
P(E) =3 6 - Hence, the probability that David will roll a number less than 4 is
.3 6
