Answer #1

Use excel formula "=BINOM.DIST(x, n, p, FALSE)"

x Excel formula P(X=x) [rounded to four decimal places]
0 =BINOM.DIST(0, 26, 0.32, FALSE) 0.0000
1 =BINOM.DIST(1, 26, 0.32, FALSE) 0.0005
2 =BINOM.DIST(2, 26, 0.32, FALSE) 0.0032
3 =BINOM.DIST(3, 26, 0.32, FALSE) 0.0120
4 =BINOM.DIST(4, 26, 0.32, FALSE) 0.0324
