How many outcomes are there if you flip a coin 3 times?
There are eight possible outcomes of tossing the coin three times, if we keep track of what happened on each toss separately. In three of those eight outcomes (the outcomes labeled 2, 3, and 5), there are exactly two heads.২ সেপ্টেম্বর, ২০১৯
How many outcomes are there when flipping 3 coins?
Now consider an experiment of tossing three coins simultaneously. The possible outcomes will be HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. So the total number of outcomes is 23 = 8.
What is the probability of getting 3 tails?
Answer: The probability of flipping a coin three times and getting 3 tails is 1/8.
What is the probability of getting least 3 heads?
N=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.
What is the probability of getting 3 heads?
Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125. When you flip a coin 3 times, then all the possibe 8 outcomes are HHH, THH, HTH, HHT, TTH, THT, HTT, TTT.
What is the probability of getting at least 2 tails when flipping 3 coins?
Listing the outcomes (H being heads and T being tails... HHH, HHT, HTH, HTT, THH, THT, TTH, TTT), it's clear that 1/2 the outcomes result in at least 2 tails.২ অক্টোবর, ২০১৯
What is the probability of getting 2 heads?
For example, the probability of two heads is 1/2 · 1/2 = 1/4, and the probability of two tails is the same. Since there are two leaves corresponding to one head and one tail, each of probability 1/4, the probability of this event is 1/4 + 1/4 = 1/2.
