Question

in a school the probability that a student takes chemistry is 0.7. the probability that a student takes english is 0.4. the probability of a student not taking either course is 0.18. A) show this information on the Venn diagram given below. B) determine weather the course of English and chemistry are independent. show this mathematically.

Answer 1

Answer:

Step-by-step explanation:

For B) :

If independent, Pr(c∩e)=Pr(c)×Pr(e) as Pr(c|e)=Pr(c)

Because 0.28=0.7×0.4, event c and e are independent of each other.

Hope this helps :)
