Question

A coin is tossed. If head comes up, die is thrown but if tail comes up, the coin is tossed again. Find the probability of obtaining: two tails (ii) head and number 6 (iii) head and an even number,

Answer 1

Correct Answer - (i) `1/8` (ii) `1/8` (iii) `3/8`
`S={ H1, H2, H3, H 4, H 5, H 6, T T, TH} rarr n(S)=8`.
(i) P(teo tails)`=1/8`.
(ii) `P`(head and the number 6) `=1/8`.
(iii) P( head and an even number) `=3/8`.
