Answer:
The probability of pulling a blue marble from the bag is;
[tex]P_B=\frac{1}{5}=0.2[/tex]
Explanation:
Given that there are 2 blue, 5 yellow, and 3 white marbles in a bag.
The total number of marbles in the bag is;
[tex]n_t=2+5+3=10[/tex]
The probability of pulling a blue marble from the bag will be;
[tex]P_B=\frac{\text{ number of blue marble}}{\text{total number of marble}}[/tex]
Substituting the given values;
[tex]\begin{gathered} P_B=\frac{\text{ number of blue marble}}{\text{total number of marble}}=\frac{2}{10} \\ P_B=\frac{1}{5}=0.2 \end{gathered}[/tex]
Therefore, the probability of pulling a blue marble from the bag is;
[tex]P_B=\frac{1}{5}=0.2[/tex]
