Question

Question 1 & 2. Please help. I also need an explanation on how you got the answer please

Answer 1

1. Drawing a diamond from a shuffled deck of 52 cards

the probability of drawing a diamond is giving for the number of diamond of the deck out of the total amount of cards in the deck

since a deck has 13 diamonds

then

`P=(13)/(52)`
`P=(1)/(4)=0.25`

then the probability is 0.25 or 25%

2. roll a dice and observing a number greater than 2

a dice has 6 sides

since this is a FAIR dice each side has the same probability

the number that are greater than 2 are

3,4,5,6

this means 4 out of 6 sides are greater than 2

then the probability of observing a number greater than 2 is

`P=(4)/(6)`
`P=(2)/(3)=0.666`

then the probability is 0.67 or 67%
