There are only red and blue cards in a box. The probability of choosing a red
und in the box at random is one third. If there are 246 blue cards, how
many cards are in the box?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given

p(red colour) = 1/3

p(blue colour) = 1-1/3 = 2/3

p(blue card) = no.of blue cards/ Total cards

2/3 = 246/ Total cards

Total cards = 246/2/3 = 369

p(red card) = red cards/Total cards

1/3 = red cards/ 369

red cards = 123
