I disagree. There are four possible combinations of three tosses (where order does not matter):
HHH
HHT
HTT
TTT
Three of these combinations will show at least one head - only by throwing three tails will you not throw at least one head.
Thus, the probability of throwing at least one head in three flips is 75%.
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
With two flips of a coin you can get two heads, two tails, a head and a tail, or a tail and a head. There are a total of four different possible outcomes, and three of them have at least one head. That's 3 out of 4, or 3/4ths. It's also 0.75 which is the probability of getting at least one head with two flips of a coin. Note that as we use the term probability here, it is zero (no chance it can happen at all), or one (it must happen), or something in between. A probability appears in the form of a fraction or decimal, and has no units attached to it.

All sides of a quadrilateral are consecutive, by definition.Not really. In the quadrilateral ABCD the sides AB and CD are opposite, but not consecutive. What is true for a quadrilateral is that any pair of sides that is opposite is not consecutive, and any pair that is not opposite is consecutive.The question asks what shape quadrilateral has 2 consecutive sides. If the question means "2 and only 2" consecutive sides the answer is that no such shape exists. If it means at least 2 consecutive sides then any quadrilateral fits the bill.If, as I suspect, the questioner meant 2 parallel sides, the answer is a trapezium.
You need at least two numbers to find an LCM. If that's 12 and 11, the LCM of consecutive integers is their product.
If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8
Pr(3 flips at least one H) = 1 - Pr(3 flips, NO heads) = 1 - Pr(3 flips, TTT) = 1 - (1/2)3 = 1 - 1/8 = 7/8

As the question is "what is the probability of getting at least one head" the correct way to answer this is to ask what is the probability of not getting any heads and then subtract this from 1.The probability of not getting a head in 4 flips = 0.54 (i.e. 0.5 * 0.5 * 0.5 * 0.5) = 1/16.Therefore the probability of getting at least one head is 1 - 1/16 = 15/16.
It is 0.6875

It is a rhombus.
No.
