1. in a table of random digits, each digit is to occur with a probability of 0.1

a.) a student examines a list of 200 random digits and counts only eleven 4s and thus claims that the table is not really random. explain the error in the students thinking

b.) how many 7s would you expect to find in a random digits table consisting of 1000 digits

(A) Just because every digit has an equal chance of appearing does not mean that all will be equally represented. (See "gambler's fallacy")

(B) The experimental procedure isn't exactly clear, so assuming a table of digits refers to a table of just one-digit numbers, each with 0.1 chance of appearing (which means you can think of the digits 0-9), you should expect any given digit to appear about 0.1 or 10% of the time.

So if a table consists of 1000 digits, one could expect 7 to appear in 10% of the table, or about 100 times.

No

Step-by-step explanation:

It does not show a function because there is no graph.
