There is an 80 percent chance of snow. if it snows there is a 10 percent chance of todd walking to the store. if it doesn't snow there is a 60 percent chance of todd walking to the store. what is the likelihood that it will not snow and todd will walk to the store?

0.12

Explanation:

Given

there is 80 % Probability that it will snow

if it snows there is 10 % Probability that Todd walk to store

If it does not snow there is 60 % chances of Todd walking to the store

Probability that it will not snow and Todd will walk to snow

all cities have a governor

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
