Question

a box contain beads of different colours there are total 200 beads in it one bead is taken at random the probability that it is blue is 0.98 then.(a), how many blue beads are there in the box . (b) some blue beads are removed from the box. now probability of the blue bead becomes 0.96. so how many blue beads are removed​

Answer 1

Answer:

a) 196 b) 4

Step-by-step explanation:

p(e) = x/200=0.98

x = 0.98 × 200

x= 196

When the Probablity becomes 0.96

x/200 =0.96

x=192

the beads removed are

196-192=4

therefore,

a) 196

b) 4
