Assume you have a bag containing 3 blue marbles & 2 red marbles

Suppose the event is to pick one red marble.

The probability of choosing one red marble =2/5 = 0.4

If you replace it in the bag & I ask you the probability of getting a red marble you will see that P(red marble) is always 2/5 = 0.4

Now if for the 2nd draw you dont replace it & I ask again the P(red), you will notice there is one red marble less & the P(red) on the second draw will be
P(red (2nd draw) = 1/4 (since the remaining in the bag are 1 Red & 3 Blues.

Joe has 10 marbles. Ken has fewer marbles than Joe. Which inequality represents the
Colt1911 [192]

Answer:

m<10

Step-by-step explanation:

Inequality is used to show comparison between two values. It helps to determine which is

• Greater than (>),

• Less than (<),

• Equal to(=),

• Not equal to,

• Greater than or equal to,

• Less than or equal to.

• Greater than is used when one value is more than the other.

• Less than is used when a value is less or smaller than another value.

• Equal to is used when both values are the same.

• Not Equal to is used when both values are not the same

Let Ken marbles= m

Remember that Ken's marbles is fewer than Joe's, that is less than Joe's marbles.

The inequality will be

m<10
