B.x2 = –4
C.3x2 + 12 = 0
D.4x2 = 16
E.2(x – 2)2 = 0
The experimental probability of winning 5 or more tickets is 90%
To do this, we simply add the probability values of the bars that have a value of 5 or more
So, we have:
P(x >= 5) = (5 + 8 +17 + 19 + 20 + 21)%
Evaluate the sum
P(x >= 5) = 90%
Hence, the experimental probability of winning 5 or more tickets is 90%
