Ajar contains 30 red marbles 50 blue marbles and 20 white marbles if you select one marble from the jar at random what is the theoretical probability of getting a red marble

3/10

Step-by-step explanation:

P(red) = red marbles / total marbles

We have 30 red marbles

total marbles = (20 white+ 50 blue+ 30 red) = 100 marbles

P(red) = 30/100 = 3/10

0.30 or 30%.

Step-by-step explanation:

This = number of re marbles / total number of marbles

= 30 / (30+50+20)

= 30 / 100

= 0.30.

answer:

c 60% on edg

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.
