Step-by-step explanation:
no tail. Hint- In order to solve such type of question we must use formula Probability (P) = Favourable number of casesTotal number of cases , along with proper understanding of favourable cases and total cases. ... If two unbiased coins are tossed simultaneously, then the total number of possible outcomes may be either.
Answer:
hope it will help you
Step-by-step explanation:
When two coins are tossed simultaneously then the possible outcomes obtained are {HH,HT,TH,TT}.
Here H denotes head and T denotes tail.
∴, a total of 4 outcomes obtained on tossing two coins simultaneously.
Consider the event of obtaining at the most one head. At most one head is obtained means either no head is obtained or one head is obtained.
The outcome favourable to no head obtained is {TT}
The outcome favourable to one head obtained is {HT,TH}
∴, the event of obtaining at most one head has 3 favourable outcomes.
These are TT,HT and TH.
∴, the probability of obtaining at most one head =43
