Aset of cards contains the numbers 1 through 20. mathieu chooses a card at random, records the number of the card, and then returns the card to the set. he conducts 200 trials of this event. based on the theoretical probability, how many times can mathieu expect to choose a multiple of 5?

There are 40 times that Mathieu would expect to choose a multiple of 5.

Step-by-step explanation:

Since we have given that

Number written on a set of cards from 1 to 20

We require the number which is a multiple of 5.

So, the set of number which is a multiple of 5 is given by

{5, 10, 15, 20}

So, probability of getting a number which is a multiple of 5 is given by

According to question, he conducts 200 trials of this event.

So, Number of times Mathieu can expert to choose a multiple of 5 is given by

Hence, there are 40 times that Mathieu would expect to choose a multiple of 5.

step-by-step explanation:

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
