If each color appears with the same probability, then there is a 1/5 chance to pick any color.
Since picking orange and picking red are mutually exclusive (if you pick orange you can't also pick red), then P(orange or red) is just the sum of their two probabilities.
1/5 + 1/5 = 2/5 or 0.4
Answer:
True.
Step-by-step explanation:
Because I looked it up. =)
Assuming the plus sign is supposed to be an equal sign, the answer is 3/2. If not, the answer is 21/10.
Answer:
Order of symmetry = 1
Step-by-step explanation:
First of all we will define rotational symmetry.
Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.
The order of rotational symmetry is how many times it matches the original shape during the rotation.
The given shape, when rotated will only have the shape like original shape after one complete rotation so the order of symmetry is one ..
