WebbRule 1: The probability that something happens must be a number between 0 and 1. Toss an astragalus once. What's the chance you get at least a 3? Solution Getting "at least a 3" corresponds to getting either a 3, a 4, or a 6. These occur 40% +40%+10% = 90% of the time so the probability is 0.9.

I guess it must be late... the answer is so simple hahaha – Louis Dec 18, 2016 at 3:51 Add a comment WebbThe difference (subtraction) is defined as follows. The set A − B consists of elements that are in A but not in B. For example if A = { 1, 2, 3 } and B = { 3, 5 }, then A − B = { 1, 2 }. In Figure 1.8, A − B is shown by the shaded area using a Venn diagram. Note that A − B = A ∩ B c. Fig.1.8 - The shaded area shows the set A − B. the only bnb sdn bhd
