The Probability that he would get at least one nestle chocolate is 19/21.
Given that:
The number of nestle chocolates = 10
The number of Cadbury chocolates = 5
And we have to find probability of getting at least one nestle chocolates when two chocolates are drawn.
What is the probability of occurring of an event?
Probability of occurring of an event is nothing but ratio of is number of favorable outcomes and total number of outcomes.
Now,
For getting at least one nestle we have two cases:
When he draws one nestle and one Cadbury chocolates, then number of ways of getting chocolates in this case =
And when he draws two nestle chocolates only , then number of ways of getting chocolates in this case =
Therefore, number of favorable outcomes =
= (10x5) + (10x9)/2
= 95
Since total number of outcomes is the number of ways of drawing two chocolates from all the 15 chocolates =
= 15x14/2
= 105
Now the required probability = 95/105
= 19/21
Hence, The Probability that he would get at least one nestle chocolate is 19/21.

Answer:
300
Step-by-step explanation:
Every week you add 50 so 50x6 is 300
Answer: B = 70°, b = 29.2; c = 29.2
Step-by-step explanation:
sum of angles in a triangle is 180
40+70 +X = 180
X is the last angle
110+x=180
x= 180-110 =70
A= 40°
B= 70°
C= 70°
the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
Answer:
1.) up
2.) (-2,-5)
3.) x = -2
4.) (-2,-5)
5.) y = -5
6.) -∞ < x < ∞
7.) -5 < y < ∞
8.) (0,0)
9.) (0,0) and (-4,0)
10.) two solutions
Step-by-step explanation:
1.) because the parabola opens upward and the vertex is down
2.) the lowest point of the parabola is (-2,-5)
3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).
4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.
5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.
6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.
7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.
8.) The parabola first crosses the y-axis at the point (0,0)
9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)
10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.
