Question

Back wth another question.. Selena and Tracey play on a softball team.Selena has 8 hits out of 20 times at bat and Tracey has 6 hits out of 16 times at bat. Based on their last performance what is the probability that both girls will get will get a hit next time at bat?

Answer 1

Selena has 8 hits out of 20 times;

The probability that Selena hits at bat is;

$\begin{gathered} Probability(S)=\frac{number\text{ of hits}}{total\text{ trial}} \\ \text{Probability(S)}=\frac{8}{20}=\frac{2}{5} \end{gathered}$

Also, Tracey has 6 hits out of 16 times;

The probability that Tracey hits at bat is;

$\begin{gathered} \text{Probability(T)}=\frac{number\text{ of hits}}{total\text{ trials}} \\ \text{Probability(T)=}\frac{6}{16}=\frac{3}{8} \end{gathered}$

Thus, the probability of both girls getting a hit next time is;

$\begin{gathered} \text{Probability ( S and T)= }\frac{2}{5}\times\frac{3}{8} \\ \text{Probability ( S and T)= }\frac{3}{20} \end{gathered}$

ANSWER: 3/20
