If one marble is randomly selected, what is the probability the marble will be yellow? A jar contains five red marbles, seven yellow marbles, nine blue marbles, and four green marbles.
Answer
A
cap p times yellow is equal to 7 over 18
B
cap p times yellow is equal to 18 over 25
C
cap p times yellow is equal to 7 over 24
D
cap p times yellow is equal to 7 over 25
Explanation
There are 5 + 7 + 9 + 4 = 25 marbles altogether, and 7 of them are yellow. The probability of selecting a yellow marble is the number of yellow marbles divided by the total: 7/25. So the correct choice is 7/25.
