Answer:
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.
Answer:
c) Percentages
Step-by-step explanation:
Percentages can be used to compare changes from one period to another.
In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.
For example, let's find percentage increase of the number of students that joined a book club using the parameters below;
Original number of students = 32
New number of students = 36
We will calculate the increase using;
Substituting the values, we have;
Increase = 36 - 32 = 4
Percentage increase = 12.5%
Therefore, the number of students in the school club increased by 12.5%.
