3x + y -2z =22
3(6) + 0 -2(-2) =22
18 + 0 +4= 22
22=22

x+5y+z =4
6 +5(0)+ -2 =4
6 + 0 +-2 = 4
4=4

x+3z=0
6 + 3(-2) =0
6 -6 = 0

Alex_Xolod [135]

Answer:

100%

Step-by-step explanation:

Probability of a product showing up in warehouse A =60%

Probability of a product showing up in warehouse B = 80%

Probability of 2 product showing up in warehouse A is

Probability of 1 product showing up in A and probability of 1 product showing up in A

A n A = 60% x 60% = 0.6 x 0.6 = 0.36 =36%

Probability of 2 product showing up in warehouse B is

Same as above

Probability of 1 product showing up in B and probability of 1 product showing up in B

B n B = 80% x 80% = 0.8 x 0.8 = 0.64= 64%

Probability of 2 product showing up in same warehouse is define as

Probability of 1 product showing up in A and probability of 1 product showing up in A or

Probability of 1 product showing up in B and probability of 1 product showing up in B

(AnA) U (BnB) =

36% + 64% = 0.36 + 0.64= 1
