Answer:
Step-by-step explanation:
Let A be the event of getting a factor of 15 when a fair spinner numbered 1 - 5 spins and B be the event that a fair coin is tossed.
The factors of 15 =
Then ,the probability of obtaining a factor of 15 is given by :-
The probability of getting a tail :-
Since both the events are independent , thus
The probability of obtaining a factor of 15 and a tail is given by :-
Hence, the required probability :
