(D) When three coins are tossed,the total number of possible outcomes is $2^3 = 8$. The sample space is $S = \{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT\}$.The event of getting 'at least one head' includes all outcomes except the one where no heads appear (i.e.,$TTT$).The number of favorable outcomes is $8 - 1 = 7$.Therefore,the probability $P$ of getting at least one head is:$P = \frac{	ext{Number of favorable outcomes}}{	ext{Total number of outcomes}} = \frac{7}{8}$.

When three coins are tossed simultaneously,what is the probability of getting at least one head?
