Question

A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag
what is the probability that the ball drawn is (í) red? (ii) not red?
​

Answer 1

Answer:

Total number of balls in the bag = 8

No. of red balls = 3

No. of black balls = 5

(i) We know that, Probability P(E) =

(Total no.of possible outcomes) /

(No.of favorable outcomes)

= 3/8

(ii) We know that, Probability P(E) =

(Total no.of possible outcomes) /

(No.of favorable outcomes)

=5/8

or [for (ii) answer only]

p(not E) =1- p(E)

p(not E) = 1- 3/8

p(not E) = 5/8

Answer 2

Answer:

The inability to retrieve a memory is one of the most common causes of forgetting. ... According to this theory, a memory trace is created every time a new theory is formed. Decay theory suggests that over time, these memory traces begin to fade and disappear.
