of which 30 are defective ones
A bulb is taken out of the gbag
aco at random find the probabilit
of the selected bult tobe agroot​

Answer 1

Answer:

Hi there,Thanks for the question!

Probability (event) = No. of favourable outcomes/ Total no. of outcomes

Here,

No. of Bulbs = 100

Therefore, Total Outcomes = 100

No. of defective bulbs = 30

No. of good bulbs = Total no. of bulbs

No. of defective bulbs = 100 - 30 = 70

Hence, No. of favourable outcomes = 70

Thus,

P (taking good bulb) = 70/100 = 7/10

$Hope \: it \: helps.$
