Answer 1

(a)

A related table with entries that are relative frequencies is formed as follows:

	Busby	Dutlier	Hutchison
Calculator	13/77=0.169	10/77=0.130	16/77=0.208
No calculator	12/77=0.156	17/77=0.221	9/77=0.117

So,

Answer is:

	Busby	Dutlier	Hutchison
Calculator	0.169	0.130	0.208
No calculator	0.156	0.221	0.117

(b)

P(Calculator) = 0.169 + 0.130 + 0.208 = 0.507

So,

Answer is:

0.507

(c)
P(Busby AND No calculator) = 0.156

So,

Answer is:

0.156

(d)
P(Dutlier) = 0.130 + 0.221 = 0.351

So,

Answer is:

0.351
