Question

Find n_R, given the following sets:

P={b,d,f,g}
Q={a,b,c,d}
R={c,e,f,g}
S={a,d,g}

a)n_R=2

b)n_R=4

c)n_R=3

d)n_R=1

Answer 1

To find n_R, we need to find the number of elements in set R, which is the intersection of sets P and S. Set R has 2 elements.

Step-by-step explanation:

To find nR, we need to find the number of elements in set R, which is the intersection of sets P and S.

Given the sets:

• P = {b, d, f, g}
• Q = {a, b, c, d}
• R = {c, e, f, g}
• S = {a, d, g}

We can find the intersection of P and S by looking at the elements that are common to both sets:

• Intersection of P and S = {d, g}

Therefore, nR = 2, which means set R has 2 elements.
