I hope this answer help you please mark me brain liest
Step-by-step explanation:
Out of 200 persons in the sample, those having atleast one dream are 200− those who had no dream, i.e. 200−36=164
Now, out of 164 people, those who belonged to group Y are 100−21=79 people.
⇒ probability that the person chosen belonged to Group Y becomes
79/ 164
Total people who recalled atleast 1 dream = all the people except the ones who recalled None.
So, Total people who recalled atleast 1 dream = 200 - 36 = 164.
Now, Total people who recalled atleast 1 dream from group Y = all the people in group Y except the ones who recalled None.
So, Total people who recalled atleast 1 dream from group Y = 100 - 21 = 79
Required probability = Total people who recalled atleast 1 dream from group Y / Total people who recalled atleast 1 dream
= 79/164
