Haipreet tosses two different coins simultaneously (say. one is of Re 1 and other of Rs 2). What is the probability that she gets at least one head?

Explanation

Let us start with taking Total number of outcomes be=4{HH,TT,TH,HT}

Let E=event of getting at least one head

Number of favourable outcomes be=3{HT,HH,TH}

P(E)=Number of favourable outcomes /Total number of outcomes

=`3/4`
