Two coins are tossed 1000 times and the outcomes are recorded as below

Based on this information, the probability for atmost one head is

A

`1/5`

B

`1/4`

C

`4/5`

D

`3/4`

Text Solution

Verified by Experts

The correct Answer is:
C
The total number of coins tossed, n(S)=1000
Number of outcomes in which atmost one head, n( E)=550+250=800
`therefore` Probability for atmost one head =`(n( E))/(n(S))=800/1000=4/5`
Hence, the probability for atmost one head is `4/5`.
