Determine whether the events are mutually exclusive. Then find the probability. Round to the nearest tenth of a percent, if necessary. 1. GAME spinning a 3 or an odd number on a spinner with 8 equally-sized sections, numbered 1-8.

2. GRAB BAG From a grab bag, a birthday child gets to randomly pick one of twenty envelopes, 10 of which contain toy store discount coupons, 8 of which contain gift cards, and 2 of which contain cash. What is the probability a birthday child selects a gift card or cash?

3. If randomly selecting one item from a drawer that contains 4 red socks, 2 black socks, 2 white socks . Find the probability of getting an item that is white or black.

Please help, i have very limited time, it would be very appreciated if you answered the 3 questions. Thank you!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

25% is the answer

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
