A necklace is made by stringing 68 beads together in the repeating pattern: red, green, white, blue and yellow. The necklace design begins with a red bead and ends with a white bead. A bead is pulled out of the necklace at random. What's the probability that the bead is red?
Number of Red beads in the Necklace - 14
Number of Green beads in the Necklace - 14
Number of Whit beads in the Necklace - 14
Number of Blue beads in the Necklace - 13
Number of Yellow beads in the Necklace - 13
No. of ways to select 1 bead from 68 = 68
No. of ways to select 1 bead from 14 read = 14
Probability of selecting a read bead = [spoiler]14/68 = 7/34[/spoiler]
