Answer:
b. -33
Step-by-step explanation:
The question is about finding the determinant of a 2×2 matrix
General formula; when given matrix A =[ b c ]
[ d e]
the determinant of A = (e×b)-(c×d)
Evaluate
(3 -3)
(-5 -6) = (-6×3) - ( -5×-3)
= (-18)- ( 15) = -33
Answer:
Step-by-step explanation:
a )
probability of a computer being ancient = .99
probability of a computer being cutting-edge =.01
probability of two selected computer being old
= .99 x .99
= .98 or 98%
b )
probability of 5 selected computers being old
= .99 x .99 x .99 x .99 x .99
= .95 or 95%
c )
probability that at least one of the five selected computers is cutting-edge
= 1 - probability of 5 selected computers being old
= 1 - .95
= .05
5 %
