Answer: The required probability is 0.615.
Step-by-step explanation:
Let A be the event that a product receives good reviews.
Let E₁ be the event that the product is highly successful.
Let E₂ be the event that the product is moderately successful.
Let E₃ be the event that the product is poor.

(a) What is the probability that a product attains a good review.
So, it becomes,

Hence, the required probability is 0.615.


- <u>1</u><u>/</u><u>3</u><u>r</u><u>d</u><u> </u><u>part </u><u>of </u><u>the </u><u>length </u><u>of </u><u>a </u><u>bamboo </u><u>is </u><u>coloured </u><u>with </u><u>red </u><u>and </u><u>1</u><u>/</u><u>5</u><u>t</u><u>h</u><u> </u><u>part </u><u>of </u><u>it </u><u>is </u><u>coloured </u><u>with </u><u>green </u><u>and </u><u>the </u><u>remaining </u><u>is </u><u>14m </u><u>is </u><u>coloured </u><u>with </u><u>yellow</u><u>. </u>

- <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>total </u><u>length </u><u>of </u><u>the </u><u>bamboo </u>

Let the total length of bamboo be x
<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>









Hence, The total length of the bamboo is 30m.
