Answer :
Answer:
0.62
Step-by-step explanation:
P(at least one coupon)
=1−P(no coupon all 6 days)
=1−(0.85^6)
≈1−0.377
≈0.623
The event is getting at least one coupon, and the complement is getting no coupon, being 0.85 and 0.15 respectively. Simply raise the complement to the power of 6 (one for each day) and subtract from 1.
