A coin is tossed 1000 times, if the probability of getting a tail is `3/8` , how many times head is obtained? 525 (b) 375 (c) 625 (d) 725

Explanation

Given

Number of times coins are tossed`=1000`

Probability of getting a tail`= 3/8`

Probability P(A)=`m/n=x/1000`

`=> x/1000=3/8`

`=> x=3000/8`

`=> x=375`

No. of heads are obtained`= 1000-375=625`
