Question

Toss three fair coins simultaneously and record the outcomes. Find the probability of getting atmost one head in the three tosses.

• A. $\frac{1}{6}$
• B. $\frac{1}{4}$
• C. $\frac{1}{2}$
• D. $\frac{1}{3}$

Answer 1

The correct option is C $\frac{1}{2}$

Toss three fair coins simultaneously and record the outcomes.The sample space is HHH, HHT, HTH, HTT, THH, THT, TTH and TTT N=8

atmost one head in 4 events

the probability of getting atmost one head in the three tosses.$P\left(E\right)=\frac{4}{8}=\frac{1}{2}$
