Answer:
0.985
Step-by-step explanation:
Given: 35% of the fish caught in a local lake had high levels of mercury.
To find: probability that at least 6 of the 10 fish caught did not contain high levels of mercury
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favourable outcomes/Total number of outcomes
Let A denotes the event that the fish caught in a local lake had high levels of mercury.
As 35% of the fish caught in a local lake had high levels of mercury,
[tex]P(A)=0.35[/tex]
Probability that at least 6 of the 10 fish caught did not contain high levels of mercury = 1 - probability that 4 of the 10 fish caught contain high levels of mercury = [tex]1-(0.35)^4=1-0.015=0.985[/tex]
