Adie is thrown. Let A be the event that the number obtained is greater than 3.Let B be the event that the number obtained is less than 5. Then `P""(AuuB)`is(1) `3/5`(2) 0 (3) 1 (4) `2/5`A. `1`B. `2//5`C. `3//5`D. `0`

Answer» Correct Answer - A
We have,
`P(A)=(3)/(6)=(1)/(2),P(B)=(4)/(6)=(2)/(3)`
and, `P(A cap B)`= Probability of getting a number 3 and less than 5
= Probability of getting `4=(1)/(6)`
`therefore P(A cup B)=P(A)+P(B)-P(A cap B)=(1)/(2)+(2)/(3)-(1)/(6)=1`
