Answer 2

The probability for getting a head and an even number is 0.25.

Explanation:

Let, (H -Head And T = Tail )

S be the sample space of the event = { (H,1) ,(H,2) ,(H,3) ,(H,4) ,(H,5) ,(H,6) ,(T,1) ,(T,2) ,(T,3) ,(T,4) ,(T,5) ,(T,6) }

∴ n(S) = 12

Let A be the event getting a head and an even number when a coin is tossed and a six sided dice is rolled

A ={(H,2) ,(H,4),(H,6) }

∴ n(A) = 3

∴
`P(A) = (n(A))/(n(S))\\P(A) = (3)/(12)\\ P(A) = 0.25`

The probability for getting a head and an even number is 0.25.
