Simplify expression 1/4 •3(8a-5b-4)-(4a+1)+4b

(8a+b-16)/4

Step-by-step explanation:

1/4×3(8a-5b-4)-(4a+1)+4b

Simplify:

-4a-1+4b+1/4×3×8a-1/4×3×5b-1/4×3×4

=1/4xax24-4a-1/4bx15+4b-1/4×12-1

=1ax24/4 -4a - 1bx15/4 +4b -1×12/4 -1

=ax24/4 -4a -bx15/4 + 4b -12/4 -1

= -4a + 24a/4 + 4b - 15b/4 -1 -3

= -4a + 6a + 4b - 15b/4 - 4

= 2a + 4b - 15b/4 - 4

= 8a + 16b - 15b - 16 / 4

= (8a + b - 16) / 4

= 8a + b - 16 / 4

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
