Q7. Two coins are tossed 250
times and the outcomes are (i)
No head =70 (ii) one head=85
(iii) Two heads =95. Find the
probability of the occurrence
of each of these events.​

Answer 1

Answer:

(1) 70/250 = 7/25

Step-by-step explanation:

(2) 85/250 = 17/50

(3) 95/250 = 19/50

Answer 2

Answer:

TOTAL 250

P(no head)=70/250

                =0.28

P(1 head )  =85/250

                =0.34

P(2 head ) =95/250

                =0.38s
