Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.

Step-by-step explanation:
A parallelogram is a family of quadrilateral which has its two opposite sides to be equal and parallel.
In the given parallelogram, the following proof can be deduced.
1. QS bisects RT: <RSQ ≅ <TQS Given
2. RV ≅ TV Definition of a bisector
3. <SRQ + < RQT = Definition of supplementary angles
4. <RQS ≅ <QST Definition of alternate angles
5. <RVT ≅ <QVT Vertically opposite angles
6. <QRS ≅ <STQ Opposite angles are congruent
7. QRST is a parallelogram Proofed
