= (5a²)³ - 4³
you can apply the cubic factorisation rule
(a³ - b³) = (a - b)(a² - ab + b²)
= [5a² - 4][ (5a²)² - 20a² + 16]
= [5a² - 4][25a⁴ - 20a² +16]
I think this is it.
hope it helps.

#1 Find P(all five cards are different types)
#2 Find P(Straight | five different types)
#3 Find P(Flush | five different types)
#4 Find P(#2 and #3 both occur)
#5 Subtract (#2 + #3 - #4) from 1 (not #1)
#6 Multiply #1 times #5
I'm not going to solve the whole thing but these steps aren't too difficult individually.
Answer:
p value = 0.0000 < 0.05
We reject H0
Hence the claim is significant
Step-by-step explanation:

MJP and PJR is EQUAL!
LJP and NJR is EQUAL
KJL and LJM is UNEQUAL!
KJR and MJP is (I'm not really sure about this one but I believe its equall!
