**Reiny**, Saturday, September 24, 2011 at 8:40ama) prob that exactly 5 out of 12 will recognize

= C(12,5)(.61)^5(.39)^7

= appr 0.0918

b)

prob = C(12,0)(.61)^0 (.39)^12 + C(12,1)(.61)^1 (.39)^11 + ... + C(12,5)(.61)^5 (.39)^7

c) prob = 1 - (answer to b)

d) prob = C(12,0)(.61)^0 (.39)^12

= .00001238
