$N=4826$ young adults were chosen as part of the sample. The responses are organised in a two-way table.

Formula's used:$P(A)=\frac{totalnumberofoutcomescorrespondingtoeventA}{numberofoutcomesinsamplespace}$

The selected person is a man, according to the inquiry. Now we must calculate the chance that the result for "nearly certain" is correct.

Therefore,$P(AlmostcertainandMale)=\frac{favorableoutcomes}{possibleoutcomes}=\frac{597}{4826}$

$P\left(Male\right)=\frac{favorableoutcomes}{possibleoutcomes}=\frac{2459}{4826}$

As a result, the conditional probability is:

$$\begin{gathered} P(Almostcertain|Male)=\frac{P(AlmostcertainandMale)}{P\left(Male\right)} \\ P(Almostcertain|Male)=\frac{{\displaystyle \frac{597}{4826}}}{{\displaystyle \frac{2459}{4856}}} \\ P(Almostcertain|Male)=\frac{597}{2459} \\ P(Almostcertain|Male)鈮�0.2428 \end{gathered}$$

As a result, the likelihood of the result being "nearly definite" is

$P(Almostcertain/Male)=0.2428$

The chosen person is female, according to the query. The next step is to calculate the probability that the result for "some chance but probability not" is correct. Therefore,

$P(Femaleandsomechance)=\frac{favorableoutcomes}{possibleoutcomes}=\frac{426}{4826}$

$P(somechance)=\frac{favorableoutcomes}{possibleoutcomes}=\frac{712}{4826}$

As a result, the conditional probability is:

$$\begin{gathered} P(Female/somechance)=\frac{P(Femaleandsomechance)}{P\left(Female\right)} \\ P(Female/somechance)=\frac{{\displaystyle \frac{426}{4826}}}{{\displaystyle \frac{712}{4826}}} \\ P(Female/somechance)=\frac{426}{712} \\ P(Female/somechance)鈮�0.5983 \end{gathered}$$

As a result, the probability that the result for "some chance but probability not" is "some chance but probability not" is $P(Female/somechance)=0.5983$
