A die is rolled 7 times. Find the probability P(of exactly 5 occurrences of 5). a. 0.09% c. 0.08% b. 3.04% d. 0.19%

I believe it might be d but I'm not sure, sorry hope I could help

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
