Flip a coin 5 times. What is the probability that heads never occurs twice in a row?
1 answer:
Answer:
Step-by-step explanation:
Given that a coin is flipped 5 times. Let us assume it is a fair coin with probability for head or tail equally likely and hence 0.50
Sample space would have possibilities
For two heads never occurring in a row favourable outcomes are
HTTTT,HTTHT,HTTTH, HTHTH, HTHTT, THTHT, THTTT, THTTH, TTHTH, TTHTT, TTTHT, TTTTH, TTTTT, TTTTH
Hence probability =
Favorable outcomes/Total outcomes=

The formula for point-slope form is y-a=m(x-c), where y and x are variables, a is simply one point in y, m is the slope, and c is simply one point in x. The first thing we can find is m, or the slope. This is found by dividing the change in y over the change in x. The equation for this is (I’ll plug the points in the equation)
Therefore, our answer is the bottom one as our slope is 1/4.
