Answer 1

Answer: $\dfrac{1}{8}$

Step-by-step explanation:

Formula : Probability = $\dfrac{\text{favorable outcomes}}{\text{total outcomes}}$

Given , Sam has 4 cards numbered 2,3,5, and 7.

His friend has 4 cards numbered 1,2,6 and 7.

If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).

i.e. Number of possible outcomes would be (S) 4 x 4 = 16

Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)

Now , the probability that they will both choose the same number would be :

$\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}$

Hence, the required probability = $\dfrac{1}{8}$
