The five patterns are: circle, plus sign, wavy lines, empty box, and star. one hundred trials were conducted, and your very impressive friend guessed right on 41 of those trials. what proportion of the cards would i expect my friend to guess correctly?

The proportion is = 0.41 or 41%

Step-by-step explanation:

Hello!

The expected proportion is calculated as "the number the event of interest has occurred"(i.e. success) divided the total of trials.

In this case, your success is the number of times your friend guessed a card correctly in 100 trials.

The proportion is = 0.41 or 41%

I hope it helps!

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

i dont know sorry
