Afair coin is tossed four times, and each time the coin lands heads up. if the coin is then tossed 1996 more times, how many heads are most likely to appear for these 1996 additional tosses?

998 heads are likely to appear

Step-by-step explanation:

When a fair coin is tossed, the probability to flip a head is 50% and to flip a tail is also 50%, so if the coin is tossed 1996 times, 0.5*1996 = 998 heads and 998 tails are likely to appear, despite the fact the coin lands heads up 4 times before, because every toss is independent of the other ones.

the solution is 12x-6y

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
