Question

tetell this question please it is very urgent tomorrow is my exam

Answer 1

Answer:

13

Step-by-step explanation:

Given that probability of picking a red card P(red card) = 2/3.

Probability of picking a black card P(black card) = 1/3.

Now, 1/3 < 2/3.

∴ Black cards are missing.

So, the number of red cards is equal to 26.

Let x be the total number of cards.

=> 26/x = 2/3

=> 78 = 2x

⇒ x = 39.

So, the number of black cards missing =52 - 39 = 13.

Hope it helps!
