Scoring a hole-in-one is the greatest shot a golfer can make. Once 5 professional golfers each made holes-in-one on the 7th hole
at the same golf course at the same tournament. It has been found that the estimated probability of making a hole-in-one is (1/2494) for male professionals. Suppose that a sample of 5 professional male golfers is randomly selected. (a) What is the probability that at least one of these golfers makes a hole-in-one on the 10th hole at the same tournament?
(b) What is the probability that all of these golfers make a hole-in-one on the 10th hole at the same tournament?
b) T</span></span></span><span>he probability that all of these golfers make a hole-in-one on the 10th hole at the same tournament =</span>(<span>1/2494</span><span>)<span>5 </span></span> which is nearly zero.
The surface area is the sum of the are of all sides. One side's area is 64 in^2 and since it's a cube, all sides will be the same. 64*6 = 384 The surface area is 384 in^2
Ok so area=162 since the triangles sides were cut out of a square, base=height area=1/2bh=162 b=h area=1/2b^2=162 times 2 both sides b^2=324 sqrt both sides b=18=h the legnth of one side is 18cm see diagram
another way, is total aera of square=areas of both triangles=162+162=324 remember area of square=side^2 so 324=side^2 sqrt both sides 18=side
