ANSWER NEEDED ASAP!According to the table below, what is the probability that the age of a student chosen at random will be 15 or younger? A) 0.74
B) 0.59
C) 0.56
D) 0.54

The correct answer is C) 0.56

Explanation:

In general terms, the probability of two or more events can be calculated by adding the probability of each event. This rule applies when an event is considered as mutually exclusive. Age is considered as a mutually exclusive event because if a random individual is selected he/she will be only one age. In this context, if you need to know the probability that a student is 15 or younger it is necessary to add the probability that a student is 15, the probability that the student is 14, and the probability that the student is 13. The process is shown below:

P (A or B or C) = P(A) + P(B) + P(C)

P =  P(13) + P(14) + P(15)

P= 0.001 + 0.25 + 0.30

P= 0.56

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

its totaly b

your welcome btw
