Answer: B. one-third

Step-by-step explanation:

Probability of picking a red marble, P(R) = 1/6

Probability of picking a yellow marble, P(Y) = 1/2

Therefore, the probability of picking a blue marble will be:

= 1 - (P(R) + P(Y))

= 1 - (1/6 + 1/2)

= 1 - (4/6).

= 1 - 2/3

= 1/3

The probability of picking a blue marble will be one third

Y podemos poner estos numeros en la equacion dado:

x + x+ 1 = 25

2x + 1 = 25

2x = 24

x = 12

x+ 1 = 13

Entonces, los enteros son 12 & 13.
