Number of tines coins tossed = 100

no. of coins = 2

therefore total number of outcomes = 200

1) no. of getting 2 heads = 25

therefore probability = 25/200

= 1/8

2)probability of getting one head = 40/200

= 1/5

3)

= probability of getting no head = 35/200

= 7/40

1/4 , 2/5 & 7/20 is probability of occurance of two heads , one head & no head respectively

Step-by-step explanation:

two coins are tossed simultaneously 100 times

Total number of Events = 100

we get two heads 25 times

Probability of getting two heads = Number of two heads/Total toss

= 25/100

= 1/4

One Head = 40 Time

Probability of getting one head = Number of one Head / Total

= 40/100

= 2/5

No heas = 35 Times

Probability of no head = Numbers of no head / Total

= 35/100

= 7/20

probability of occurrence of each of these events

1/4 , 2/5 & 7/20
