PSYCHO15rus [73]

Answer:

Statements:                                                 Reasons:

1) ∠2 and ∠4 are vertical angles               given

2) limes <em>m </em>and <em>n </em>intersect at <em>P                    </em>definition of vertical angles

3) ∠3 and ∠4 are linear pair                       definition of linear pair

4) ∠2 and ∠3 are linear pair                       definition of linear pair

5) m∠3 + m∠4 =180                                     angle addition postulate

6) m∠2 + m∠3 =180                                     angle addition postulate

7) m∠2 + m∠3 = m∠3 + m∠4                   substitution property

8) m∠2 = m∠4                                             subtraction property

9) ∠2 ≅ ∠4                                                 definition of congruent(≅) angles

Four girls and six boys are in a Spanish club. Three of the people will be chosen at random to represent the group in a photogra
snow_tiger [21]

Answer:50 %

Step-by-step explanation:

Given

There are 4 girls and 6 boys in a club

Probability of choosing 1 girl and 2 boys is

=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}

No of ways of choosing 1 girl and 2 boys=^4C_1\times ^6C_2

P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}

P=\dfrac{4\times 15}{10\times 3\times 4}

P=\dfrac{15}{30}=\frac{1}{2}

i.e. 50\%
