Answer: The correct option is (C) [tex]\dfrac{13}{18}.[/tex]
Step-by-step explanation: Given that a bucket holds 10 white golf balls, 3 pink golf balls, and 5 yellow golf balls. Jason selects 1 golf ball from the bucket at random.
We are to find the probability that the golf ball he selects is white or pink.
Here,
number of favourable cases
= no. of white balls + no. of pink balls
= 10 + 3
= 13,
And total number of cases = total no. of balls = 10 + 3 + 5 = 18.
Therefore, the required probability that the golf ball he selects is white or pink is given by
[tex]P=\dfrac{\textup{no. of favourable cases}}{\textup{total number of cases}}\\\\\\\Rightarrow P=\dfrac{13}{18}.[/tex]
Thus, the required probability is [tex]\dfrac{13}{18}.[/tex]
Option (C) is correct.
