Answer 1

Step-by-step explanation:

On tossing two coins simultaneously, let the sample space be S.

Therefore, n(S) = 36

Let A be the event of getting 7 as a sum two numbers on the upper surface of the dice

A= {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6,1)}

$\therefore \:n (A) = 6 \\ now \\ P(A) = \frac{n (A)}{n (S)} = \frac{6}{36} = \frac{1}{6}$
