Answer:
1 in 41,539,806.
Step-by-step explanation:
The number of ways to pick 5 numbers from 45 = 45C5
= (45*44*43*42*41) / (5*4*3*2*1)
= 1,221,759.
There are 34 ways to pick a gold ball so total number of ways to get 6 matching numbers is
1221759*34
= 41,539,806.
Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
