Answer:
0.0482
Step-by-step explanation:
Given the following :
Probability of success : p(success) = 0.25
Number of trials = 800
X = number of successes
Calculate P(X > 220)
The problem above can be solved using the binomial probability formula:
P(X > 220) = P(X = 221) + P(X =222)... + P(X =800)
To save computation time, we coild use the online binomial probability calculator :
P(X > 220) = 0.0482
The binomcdf function of a graphing calcukatur can also be used :
1 - binomcdf(800, 0.25, 220)
1 - (0.95177363855) = 0.04822
Given x ^2 −3x+2=0
x ^2 −2x−1x+2=0
(Resolving the expression)
x(x−2)−1(x−2)=0 (Taking common factors)
(x−2)(x−1)=0 (Taking common factors)
∴x−2=0 or x−1=0 (Equating each factor to zero)
∴x=2 or x=1
∴2 and 1 are the roots of x ^2 −3x+2=0
