Question

A single card is drawn at random from a standard 52 card deck. Work out the following probabilities in their simplest form: P(7) = P(not 7) =

Answer 1

no of 7=4

total no of card =52

total not no.7=52-4=48

Explanation:

probability of getting 7=4/52=1/13

probability of not getting 7=48/52=12/13

Answer 2

`1) (1)/(13) \\ 2) (12)/(13)`

Explanation:

to understand this

you need to know about:

• simple probability
• PEMDAS

tips and formulas:

• there are 4 "7" cards in a deck

let's solve:

according to the question

• P(7)=4/52
• P(7)=1/13

according to the question

• P(not 7)=1-
  `(1)/(13)`
• P(not 7)=12/13
