Match manufacturers find that 5% of the matches in a box are defective determine the probability that out of a box containing 50 match sticks 1) Non will be defective.
2) If the guarantee is not more that in four will be defective what is the probability that the box will meet the guarantee quality?​

step-by-step explanation:

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
