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
