If you have five red balls and five blue balls in a jar what’s the probability of the first ball being red?

rosijanka [135]

Answer:

red balls = 5

blue balls = 5

total balls = 5 blue+5 red

= 10

$p(first \: ball \: being \: red) = \frac{red \: balls}{total \: balls}$

$p(first \: ball \: being \: red) = \frac{5}{10} = \frac{1}{2}$
