The frequency table above shows the distribution of the actual number of fluid ounces of water in a random sample of 8020 -ounce bottles of the water at a bottling plant. Bottles are only sold if they contain at least 19.8 but no more than 20.2 fluid ounces of water. If the proportion of bottles that can be sold is the same for the sample and the 16,000 20-ounce bottles produced at the plant each day, how many of the 16,000 bottles cannot be sold?

The probability of an unfair coin landing heads side up is 0.6. A student tossed this coin into the air 9 times. It landed tails side up 5 times and heads side up 4 times. What is the probability that the coin will land heads side up on the 10th toss?

When a coin is flipped, it has unequal chances of landing heads-up or tails-up. • A Bernoulli trial is a random experiment with two possible outcomes, which are commonly referred to as success and failure, or the numeric values 1 and 0.
A fair coin has one tail and one head. Both of these outcomes have an equal chance of being the event's final outcome. For an unfair coin, the probability of seeing heads is 2/2 or 1. Similarly, the likelihood of a tail on an unfair coin is 2/2 or 1.
When a coin does not behave like a standard coin, it is said to be an Unfair Coin. Unfair Coin does not have the same outputs as a regular coin, for example, an Unfair Coin has either two heads or two tails.

The function is defined by . What is the value of f(3) ?
