Question

if a coin is thrown three times what is the probability of getting heads all three times?​

Answer 1

When we toss three coins simultaneously then the possible of outcomes are: (HHH) or (HHT) or (HTH) or (THH) or (HTT) or (THT) or (TTH) or (TTT) respectively; where H is denoted for head and T is denoted for tail.

Therefore, total numbers of outcome are 23 = 8

The above explanation will help us to solve the problems on finding the probability of tossing three coins.

P(getting three heads) = P(E1)

Number of times three heads appeared

= Total number of trials

= 70/250

= 0.28..

Answer 2

Let heads be represented by h and tails by t.

All possible outcomes of three throws= (h,h,h);(h,h,t);(h,t,t);(h,t,h);(t,h,h);(t,t,h);(t,h,t);(t,t,t).

Number of outcomes=8

Favourable outcome=7

Probability=7/8
