​

Answer 1

Answer:

Given:

Alex selects a positive even integer less than 20.

Bob picks a positive multiple of 3 less than 30.

And they both pick the same number.

\begin{gathered} \\ \Large{\bf{To\: Find\::}} \\ \end{gathered}

ToFind:

The probability of given case.

\begin{gathered} \\ \Large{\bf{Solution\::}} \\ \end{gathered}

Solution:

➣ Alex selects a positive even integer less than 20.

Thus,

Favourable outcomes are,

➠ 2, 4, 6, 8, 10, 12, 14, 16, 18

Again,

➣ Bob picks a positive multiple of 3 less than 30.

Thus,

Favourable outcomes are,

➠ 3, 6, 9, 12, 15, 18, 21, 24, 27

Hence,

Total possible outcomes are,

➠ 2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 21, 24, 27

Therefore,

➠ Total no. of possible outcomes = 15

According to the question,

➣ They both pick the same number.

So,

The favourable outcomes are,

➠ 6, 12, 18

Therefore,

➠ Total no. of favourable outcomes = 3

As we know that,

\begin{gathered}\orange\bigstar\:{\Large\mid}\:\bf\purple{Probability\:=\:\dfrac{Total\:no.\:of\: favourable\: outcomes}{Total\:no.\:of\: possible\:outcomes}\:}\:{\Large\mid}\:\green\bigstar \\ \end{gathered}

➠ Probability = \begin{gathered}\tt{\dfrac{3}{15}} \\ \end{gathered}
