A single card is drawn at random from a standard 52 card deck. Work out the following probabilities in their simplest form: P(5)= and P(not 5)=

There are four 5's in a deck of cards

The probability of being a 5 would be 4/52 which simplifies to 1/13

The probability of not being a 5 would be 1 - 1/13 = 12/13

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

factor trees are nice.
