In exercises 1-54 express each probability as a fraction reduced to lowest terms. In Exercises 27–34, you select a family with three children. If M
represents a male child and F a female child, the set of equally
likely outcomes for the children's genders is {MMM, MMF, MFM,
MFF, FMM, FMF, FFM, FFF}. Find the probability of selecting a
family with
27. exactly one female child.
28. exactly one male child.
29. exactly two male children.
30. exactly two female children.
31. at least one male child.
32. at least two female children.
33. four male children.
34. fewer than four female children.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
