Question

claire flips a coin 4 times. using the table, what is the probability that the coin will show tails at least once?

0.06
0.25
0.69
0.94

Explanation:

Step1: Recall the complement rule

The probability of an event \(A\) (tails at least once) and its complement \(\overline{A}\) (tails 0 times) satisfy \(P(A)=1 - P(\overline{A})\)

Step2: Identify the probability of the complement event

From the table, \(P(\text{tails }0\text{ times}) = 0.06\)

Step3: Calculate the probability of tails at least once

\(P(\text{tails at least once})=1 - 0.06=0.94\)

Answer:

\(0.94\)
