When Hugo is serving at a restaurant, there is a 0.03 probability that each party will request a high chair for a young child. During one hour, Hugo served 10 parties.
Assuming that each party is equally likely to request a high chair, what is the probability that at least one party will request a high chair?
Round your answer to the nearest hundredth.

Respuesta :

Answer:

.26

P=(at least one high chair)

= 1−P(none of 10 with high chair)

= 1−(0.97)

     10

≈ 1−0.7374

≈ 0.2626

Rounded to the nearest hundred is .26
