The probability that kebba, Ebou and Omar will hit a target are \(\frac{2}{3}\), \(\frac{3}{4}\) and \(\frac{4}{5}\) respectively. Find the probability that only Kebba will hit the target.
A
\(\frac{2}{5}\)
B
\(\frac{7}{60}\)
C
\(\frac{1}{30}\)
D
\(\frac{1}{60}\)
correct option: c
Hence the probability that only Kebba will hit the target
= P(K)xP(E')xP(O')
= (\frac{2}{3} \times \frac{1}{4} \times \frac{1}{5})
= (\frac{1}{30})
