two coins are tossed simultaneously 100 times and we get two heads 25 times,one head 40 times and no head 35 times.Find the probability of occurrence of each of these events.
Answers
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
