Step-by-step explanation:
Ask your teacher what the heck is going on in this problem. It really doesn't make any sense.
Answer:
I think that the ADA (Americans with Disabilities Act) has explicit regulations on slopes and ramps so that people with disabilities can go about their daily life easier, and to guarantee the safety and wellbeing of the disabled. If, for instance, a wheelchair ramp were too steep, there would be a danger of the wheelchair rolling down too quickly, or the person falling backward on their way up.
In a single toss, the probability that the result of the toss is head is 1/2:
For 2 tosses in a row, the probability that the result is head in both tosses is
If we continue, we find that the probability to have 4 heads in 4 consecutive tosses is given by
Divide the numerator and denominator by 3:
15 / 3 = 5
24 / 3 = 8
5/8
