Question

Three coins are tossed simultaneously 200 times with the following frequencies of different

outcomes:

Outcome 3 heads 2 heads 1head No head

Frequency 23 72 77 28

If three coins are simultaneously tossed again, compute the probability of 3 heads, 2 heads,1 head, No head coming up​

Answer 1

Answer:

Step-by-step explanation:

Total number of tosses of three coins simultaneously=200

Number of outcomes of 2 heeads =72

probability of two heads coming up= number of 2 heads/ total number of trials

                                                         =72/200 =9/25
