For
(c+d)(ex+f)
the expanded form is
dex^2+dex+cfx+df
(ce)x^2+(de+cf)x+(df)
ax^2+bx+c
the value of a is ce
the value of b is de+cf
the value of c is df
so
(-2x+3)(x+8)
(-2x+3)(1x+8)
b is 3*1+-2*8=3-16=-13
answer is -13
so pick 13 because we have -B, so B=13
There would be 0.07923 probability to get 4 aces.
<h3>What is probability ?</h3>
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Total number of cards in deck = 52
Total number of aces = 4
When 5 cards are chosen randomly,
The probability to get 4 aces
= 1/52+1/51+1/50+1/49+0
Since, at 5th time there will be no ace remains, so probability would be 0.
= 0.01923+0.01960+0.0200+0.0204
=0.07923
