Answer 1

HEY!!

7. 4^x-4^x-1=24

x+(x-1)=24

x+x-1=24

2x-1=24

2x=23

x=23/2

x=11.5

11. total outcomes = 26

favourable outcomes=2

p ( 2 of red)= 2/26

= 1/13

total outcomes=52

favourable outcomes =12

p (face cards)=12/52

=6/26

= 3/13

total outcomes = 26

favourable outcomes = 1

p(black king) = 1/26

total outcomes=52

favourable outcomes = 4

p(an ace ) = 4/52

=2/26

= 1/13
