Question

A bag contains 4 red 6 blue and a second bag contains 4 blue and 6 green balls. A ball is taken out from each bag. find the probablity that one ball is red and other ball is green the probability that an event A happens in one trail of an experiment is 0.4 three independent trails of the experiment are performed. find the probablity that the event A happens at least one​

Answer 1

Answer:

2

Step-by-step explanation:

l said simply i think it id correct

Answer 2

Step-by-step explanation:

Number of green balls = 7

Number of red balls = 2

Number of blue balls = 5

Total number of balls = 14

P(E) = Number of Favorable Outcomes/Total Number of Possible Outcomes

Or number of event occurs/total number of events

So, probability of drawn balls that it is either a blue or a green

P(E) = (7+5)/14 = 12/14 = 6/7

hope it help
