Question

Three coins are tossed simultaneously 250 times. The distribution of various  outcomes is listed below: (i) Three tails: 30 (ii) Two tails: 70 (iii) One tail: 90 (iv) No tail: 60 Find the respective probability of each event and check that the sum of all  probabilities is 1.​

Answer 1

Answer:

Step-by-step explanation:

Total tosses=250

i. 30/250 =3/25

ii. 70/250=7/25

iii. 90/250=9/25

iv. 60/250=6/25

Respective probability of each event = 3/25+7/25+9/25+6/25

=25/25 =1
