You randomly draw a marble from a bag of marbles that contains 8 88 blue marbles, 5 55 green marbles, and 8 88 red marbles. What is P(draw a blue or red marble ) P(draw a blue or red marble)start text, P, left parenthesis, d, r, a, w, space, a, space, b, l, u, e, space, o, r, space, r, e, d, space, m, a, r, b, l, e, end text, right parenthesis? If necessary, round your answer to 2 22 decimal places.

7%

Step-by-step explanation:

add all numbers up get 21 then divide by 3 and get 7

0.25

Step-by-step explanation:

3 favorable outcomes

3+4+5=123 + 4 + 5 = 12

3+4+5=12

3, plus, 4, plus, 5, equals, 12

total marbles

P(draw a blue marble)=

12

3

=0.2

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.
