Step-by-step explanation:
No. of times you tossed a coin=150
Percentage of times tail comes=40%
No. of times you tossed tail =40% of 150
=40/100×150
=60
no. of times you tossed head=?
no. of tails+ no. of heads = Total no. of tosses
no. of heads =total no. of tosses - no. of tails
=150-60=90
Therefore,no. of times you tossed heads is 90 .
