Question
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?
- 0.4
- 0.5
- 0.6
- 1
The correct answer is: 0.6
HINT: Tossing of a coin is an independent event.
Complete step by step Solution
Since tossing of a coin is an independent event, the previous flips won't affect the forthcoming flips.
Given that the probability of an unfair coin landing heads side up = 0.6.
Since it is an independent event, the probability that the coin will land heads side up on the 10th toss is also 0.6.
Hence option C is the correct answer.
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.

Two beach balls are each in the shape of a sphere. The larger beach ball has a diameter of 3x, and the smaller beach ball has a diameter of x. What is the ratio of the volume of the larger beach ball to volume of the smaller beach ball?
volume of a sphere
A sphere is a collection of points in space separated by r from the center. The quantity of space a solid in three dimensions takes up is known as its volume. The unit of volume is measured in cubic (in3, ft3, cm3, m3, et cetera). Before calculating the volume, ensure all measurements are in the same unit.
Follow the steps below to determine the volume of a given sphere:
Step 1: Compare the radius of the given sphere. If you know the diameter of the sphere, divide it by two to get the radius.
Step 2: Find the radius of r'³s cube.
Step 3: Now divide it by (4/3) π
Step 4: The volume of the sphere will be the final answer.
The volume V of a sphere is equal to four-thirds of pi times the cube of the radius.
V = 4/3πr³
A hemisphere's volume is equal to one-half that of its related sphere.
