Answer:

50%

Step-by-step explanation:

So, we divide by another 2! to cancel out double counting of two T's. Finally, if we divide all 6 different ways of getting exactly 2 heads (and 2 tails) in 4 flips by all possible outcomes 2 * 2 * 2 * 2 = 16 we would get the probability of exactly 2 heads in 4 flips.

vitfil [10]

Answer:

f(-3)= <em><u>-</u></em><em><u>5</u></em>

g(4)= <em><u>7</u></em>

Step-by-step explanation:

here f(x)= -5, clearly it's not depending on 'x' ,so it will have same value,for all x

i.e, f(-3) is also -5

and, g(x)=2x-1

to get g(4) put x=4 in <u>2</u><u>x</u><u>-</u><u>1</u>

i.e, (2×4)-1 =7
