Red beads = 3

Black beads = 2

White beads = 5

Total beads = 10

Probability of drawing a red bead = 3/10

= 0.3

Probability of drawing either a red bead or white bead

Red + white = 8

Probability of drawing either a red bead or white bead = 8/10

= 0.8

Probability of drawing a black bead = 2/10

= 0.2

.... Hope this will help....

The number of blue beads are not given,

So that I could find the probability of drawing a blue bead

Total outcomes=3+2+5=10

(I) probability of getting a red bead=3/10
(ii) probability of getting a blue bead=0
(iii)probability of getting either a red bead or a white bead=3/10 or 5/10
(iv)probability of getting a black bead=2/10=1/5
