(4)/(10)

Step-by-step explanation

To calculate the probability of event A, divide the number of outcomes favorable to A by the total number of possible outcomes.


P(A)=\frac{favourable\text{ outcomes}}{total\text{ outcomes}}

so

Step 1

a)let


\begin{gathered} favourable\text{ outcomes=red balls = 4 \lparen there are 4 red balls\rparen=4} \\ total\text{ outcomes= total balls= 4 red+6 green=10 balls=10} \end{gathered}

b) now, replace in the formula and simplify

.


P(A)=(4)/(10)=(2)/(5)

therefore, the answer is


(4)/(10)

I hope this helps you
