It is given that

Number of trials = 300

Consider E1, E2, E3 and E4 as the events

(i) So we get

P (E1) = number of times 3 head/ number of trials

By substituting the values

P (E1) = 54/ 300

We get

P (E1) = 0.18

(ii) So we get

P (E2) = number of times 6 head/ number of trials

By substituting the values

P (E2) = 33/ 300

We get

P (E2) = 0.11

(iii) So we get

P (E3) = number of times 5 head/ number of trials

By substituting the values

P (E3) = 39/ 300

We get

P (E3) = 0.13

(iv) So we get

P (E4) = number of times 2 head/ number of trials

By substituting the values

P (E4) = 60/ 300

We get

P (E4) = 0.2
