Calvin throws 12 sheets of paper up in the air and randomly catches one of the sheets as they float down. Of the 12 sheets of paper, 9 are white and 3 are red. The probability that Calvin caught a white sheet is . It is that this event occurs. The probability that Calvin caught a red sheet is . It is that this event occurs.

Respuesta :

Total number of sheets are 12.

Total number of white sheets= 9

Total number of red sheets = 3

Probability = Number of favorable outcomes/ total number of outcomes.

Hence

When Calvin throws the sheets in the air, the probability that he gets a white sheet is

[tex]\frac{9}{12}[/tex]

which equals to [tex]\frac{3}{4}[/tex]

that becomes 0.75
