Answer 1

Step-by-step explanation:

Number of blue marbles: 3

P(blue): 3/10

P(red): 4/10 or 2/5

Total number of marbles: 10 (you can get this from 3+3+4 = 10)

Number of red marbles: 4

Answer 2

There are 4 red, 3 blue and 3 yellow

3/10= P(blue)
3= number of blue marbles
10= total number of marbles
2/5=P(red)
4=number of red marbles

P(colour) essential at means the probability of drawing that colour of marble out. E.g. probability of drawing a red is 4/10 or 2/5.
