Question

help me finding answer​

Answer 1

Answer:

0.115,0.475,0.36

Step-by-step explanation:

(1) Probability=favourable outcome/total outcome

favourable outcome=23

total outcome=200

P(getting 3 heads)=23/2=0.115

(2) Probability=favourable outcome/total outcome

favourable outcome=72+23

total outcome=200

P(at least two heads)=95/200=0.475

(3) Probability=favourable outcome/total outcome

favourable outcome=72

total outcome=200

P(two heads and one tail)=95/200=0.36
