The probability that a male professional golfer makes a hole-in-one is 1/2780. Suppose 36 professional male golfers play the six
yuradex [85]

Answer:

The right solution  is "9.7\times 10^{-10}".

Step-by-step explanation:

According to the question,

The probability that male professional golfer makes hole in one will be:

P=\frac{1}{2780}

Number of players,

n = 36

and,

q=1-P=\frac{2779}{2780}

By using the Binomial theorem, we get

⇒ P(x=r) = \binom{n}{r} p^r q^{n-r}

Bu substituting the values, we get

                   =\binom{36}{4} (\frac{1}{2780} )^4 (\frac{2779}{2780} )^{32}

                   =9.74929\times 10^{-10}

or,

                   =9.7\times 10^{-10}

Given that B, D and F are midpoints, find the length of segment DA.
TiliK225 [7]

Answer:

The length of segment DA is 15 units

Step-by-step explanation:

  • <em>The segment which joining a vertex of  a triangle and the midpoint of the opposite side to this vertex is called a median </em>
  • <em>The point of intersection of the median of a triangle divides each median into two parts the ratio between them is 1: 2 from the base, which means </em><em>the length of the median is 3 times the part from the base</em><em>  </em>

Let us use this rule to solve the question

In Δ AEC

∵ D is the midpoint of EC

∴ AD is a median

∵ B is the midpoint of AC

∴ EB is a median

∵ F is the midpoint of AE

∴ CF is a median

→ The three medians intersected at a point inside the triangle,

   let us called it M

∵ AD ∩ EB ∩ CF at M

∴ M is the point of intersection of the medians of Δ AEC

→ By using the rule above

∴ AD = 3 MD

∵ MD = 5

∴ AD = 3(5)

∴ AD = 15 units
